"The hole was still caving in and I didn't care. I just wanted my brother, man," said a weeping Jeremy Bush.

Hillsborough County Sheriff's Deputy Doug Duvall, who was firstto arrive on the scene, had never seen anything like it. He said he grabbed onto Jeremy, "and was actually able to reach down and grab his hand and pull him out of the hole. The hole was collapsing and at that time we left the house."

Fire rescue workers evacuated the rest of the family safely.

But equipment showed the 30-foot wide, 20-foot deep hole was still growing beneath them. They've sent in specialized equipment, including sound sensors and cameras, but the results are not promising.

"The listening devices are designed to essentially hear the sound a mouse would make walking across the floor. They're that sensitive. They did not detect any signs of life," said Chief Rogers.
